Yes, in 2026, the City of Denver requires a permit if the deck is more than 30 inches above grade, exceeds 200 square feet, or is attached to the house. Small, detached, ground-level platforms under 200 sq ft may be exempt from building permits but still require zoning review.
Composite decking typically costs between $30 and $60 per square foot installed, while pressure-treated wood ranges from $15 to $35. However, premium cedar or redwood decks in Denver can start at $85 per square foot due to high demand and material quality.
Denver calculates fees based on project valuation. For a typical $12,000 to $25,000 deck project, permit fees generally range from $115 to $600, including plan review and building permit costs.
Denver's high UV exposure and snow loads require specific engineering. Homeowners often pay a 10-15% premium for weather-resistant materials like capped composite or modified concrete mixes for footings to handle the city's extreme temperature swings.
